It shoots a very fast projectile with a flower shape and rainbows
It does 25-35 damage (i think)
It penetrates a few enemies
And it has a slight +Grow
Also, because its a rifle it gets a lot of ammo, which makes it basically impossible to run out

Basically, pretty boring, but thats just about any weapon (including the robo-beam, which is also amazing)

This is kind of in the neutral zone, but +Heavy Rounds, doesnt work too bad, but neither does it work good

The fast base speed can make Heavy Rounds a bit better, but +Speed is basically worthless

The only thing that doesnt really work with it atool is +Accuracy
(to be honest, the mod is kind of useless most of the time)

As far as i know, there arent any bad artifacts for the weapon

it already becomes pretty good when you add some
+Pierce or +Fire Rate or even some +Damage if you are a rebel

There are also a few silly combo's like 3 +Ricochet, 3 +Firerate and 2 +Homing with a +Pierce
that open up a lot of combinations with different artifacts, for instance

3 Ricochet + Fire/Flaming Artifact, will set tight corridors completely in flames
3 Firerate + any explosive artifact, everything explodes
2 Homing + Pierce + basically any artifact (except Laser or crystal )

Now we get into the good stuff

Split + any explosive artifact, is a really good base for bombardment

a Sun or Crystal artifact are probably the best artifacts for a good base

Remember that Crystal artifact?
Add +Pierce +Split and +Spread
and prepare to fill your entire screen with light blue flowers, because it is absolute carnage when you use this gun, (If you say "Screw it!" and you dont believe in flowah stafh, you can buy an old cane to get your game to nearly crash)

Sun artifact + 2 Spread + Split
Sun artifact + 2 Split + Spread

Try it
im pretty sure you could consider it the power of 10 superguns

its hard to make these expiriments, but i will do them anyways
also, new mods/artifacts will make this guide exponentionally bigger i suppose
